Triceps vs. Biceps

By Jaxson

Main Difference

The main difference between Triceps and Biceps is that the Triceps is a arm muscle and Biceps is a muscle of the arm.

  • Triceps

    The triceps, also triceps brachii (Latin for “three-headed muscle of the arm”), is a large muscle on the back of the upper limb of many vertebrates. It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).

  • Biceps

    The biceps, also biceps brachii (Latin for “two-headed muscle of the arm”), is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm. While the biceps crosses both the shoulder and elbow joints, its main function is at the elbow where it flexes the forearm and supinates the forearm. Both these movements are used when opening a bottle with a corkscrew: first biceps unscrews the cork (supination), then it pulls the cork out (flexion).
